When a wire is bent back and forth, the continuous bending causes internal friction between the atoms of the wire, which generates heat due to the energy released from the bending motion. This phenomenon is known as mechanical hysteresis, where the repeated bending and unbending of the wire causes it to heat up.
What else can I help you with?
How does ac current move in a wire?
AC current moves in a wire by periodically reversing direction, flowing back and forth in response to the alternating voltage source. The electrons in the wire oscillate back and forth, creating an electric field that propagates through the wire and carries the energy along with it.
What happened to the material when bent in electric wire?
When an electric wire is bent, the material comprising the wire undergoes deformation. The atoms within the material shift positions as the wire is bent, causing a change in its physical structure. This deformation can affect the wire's electrical conductivity and mechanical properties.
What happens when you move a magnet back and forth inside a coil of a wire?
When you move a magnet back and forth inside a coil of wire, it induces an electric current to flow in the wire. This process is known as electromagnetic induction and is the principle behind how electric generators work. The strength of the induced current is determined by the rate of change of the magnetic field.
What happens to the direction of the current when you move the magnet back and forth?
When you move the magnet back and forth near a coil of wire, it induces an alternating current in the wire. The direction of this induced current changes as the magnet moves due to Faraday's law of electromagnetic induction, which states that changing magnetic fields induce an electromotive force (emf) in a conductor.
What will happen to wire if it is bend?
When a wire is bent, it can weaken or break due to the stress placed on it. If the wire is made of a material like copper, repeated bending can cause it to become brittle and potentially break. Additionally, the electrical conductivity of the wire may be affected if it is bent too severely.
When a wire is bent back and forth it becomes hot why?
When a wire is bent back and forth, it causes deformation in the metal structure, leading to an increase in resistance. This increased resistance results in heat being generated as electrical current flows through the wire. With repeated bending, the accumulated heat can cause the wire to become hot.
Why copper wire becomes stronger when bent?
It becomes weaker and breaks when bent many times.
When a wire is bent to form a square its area becomes A square cm square What is length of the wire?
(4 times the square root of 'A') centimeters.

A horseshoe magnet is moved back and forth across a piece of copper wire an electric current is detectable in the wire?
yes, it will be very small but the inductance from the magnet should stimulate a current in the wire as it will cause electrons to move.
Largest area Is included when the wire is bent into the shape of?
A circle.

How do you access door lock 2002 Lexus LE?
Remove interior door trim panel. The lock cylinder is bolted to the backside of the outside door handle. Release rod clip, unplug the security wire and the twist the lock back and forth until it becomes free.
Meaning of wire?
Wire is a metal that is made so thin it can be bent. There are many types of wire including, copper, aluminum and gold.
